Well, so it is a BIOS bug, and that is the end of research in this direction...
Either syslinux (that seems to be better but for which I need help) or RDISK+SUBST (that I know, but may be a bit clumsy) Thanks, Alain Em 17-05-2011 15:05, Jack escreveu: > > Alain, > >> I just foud how to make it work (kind of...) >> >> I boot normally, single-stepping, loading all *except UIDE*, than I do: >> SET COMSPEC=C:\COMMAND.COM (it's the same) >> C: >> DEVLOAD A:\DOS\UIDE.SYS /D:CDROM >> >> it loads, and I can access drive C:, but if I access A: it locks just >> the same, with the HardDisk led on. >> >> ==>> so, imho, the drive A: is disapearing when UIDE is loaded.
